Further, authors in [1]} addressed network slicing related concepts i.e. resource allocation, virtualization technologies, orchestration process, and isolation function. The paper provided a comprehensive discussion on Software Defined Networking (SDN) and Network Function Virtualization (NFV) along with a deployment use-case (which considers network slicing using both NFV and SDN integration). The authors further demonstrated existing challenges and future research directions of network slicing implementation in 5G communication system. Moreover, a comprehensive survey on architecture and further research directions of network slicing is also available in [2]}.
